within such shell,

pipe 13 extends only part way up. into the ooster shell 14, but abovethe water level therein, and is conveniently surmounted by.

the shell 16 direct the water discharged from the pipe 13 toward thebottom of the shell 14, and allow this water to be separated from theair with which it is mixed. A second pipe 20 projects up through thebottom of the shell 14, and its upper endis surrounded by a hood Vorcylinder 21- spaced from the p1 e 2() and closed4 at its upper end. Thecy inder 2l is open at its lower end, being supported above the fioor ofthe shell 14 by legs 2 2, or in some other convenient manner. The pipe20 communicateswith the space in the shell 14 by this open lower end ofthe cylinder 21, such end being below the water levell in the shell 14.The pipe 20 may be connected, preferably through a check valve 23 whichprevents back lflow, with a suitable storage reservoir 24, shown as atank supported on a suitable framework above the evel of the ground, theconnection between the i e 20l and thetank 24 including, if nec- P Pessary,'a horizontal pipe 25 which extends a considerable distance and avertical pipe 26 which leads'ffrom the pipe 25 to the reservoir 241-Horizontal pipe's25 up to nearly a mile in length have been used andvertical pipes up to sixty o r seventy' eet high. A third p1pe 30 alsoeXtendsinto the shell 14, communicating with the uiper part of the spacemanualvalve 31 which can be ad'usted inanually to give any desired outet opening through the pi e 30, for permitting the def# art o totheatmosphere, and maybe of anydesired height above the ShellV 14.

Theshell 14 is also girovided at its up er part with a/spring sa ety or'blow-oiva ve 35,.which opens outwardlyto escape from4 the-upperpart -o'the sliell 14 when vthe 'pressure 1`n suchfshell exceeds Vapredetermined value." Th'i's.safety.valve` is, v to take care ofany-abnormalpressre :con-4 ditions, especially thosewhich occur when thesystem is started into' operation.l

In operation, the 69m ressed air discharged by the nozzle.1 2 mixe swith the water in the well tovfrin aii'emulsion which overflows-thetopof the pipe 13 into the shell or, Vc higtmber 14. When so discharged`this 'emulsion separates-within thebooster shell 14 in toits-constituents air an L'Water, the water fallingto the bottom and the airrising to the top of the shell 14. The se aration is made more e'ectiveand 'comp ete by reason of' the upward discharge of this overflowing airand water against the under rmitfair to.

side of the umbrella 15, which defiects the water downward and againstthe open ended cylinder 16 and provides an excellent opportunity for theair to escape from the water. The pressure of this separated air on theupper surface of the water causes the latter to flow up throughthe'bottom of the cylinder 21 and into the pipe 20, the entrance to thepipe 2() being either at the top thereof or through slots 38 with whichsaid pipe is preferably provided within the cylinder 21.

.he ressure of the ai;1 on the water is suiiiclent y great to force thiswater through the pipe 20 and the checkvalve 23- arld through S thehorizontal pipe 25 add vertical ipe into the tank 24. The air which colects in the upper part of the bo'oster shell 14 is vpermitted to escapethrough the pipe 30, but the valve 81 is adjusted manually so that theesca e of air is suflicient to prevent an excess of air within thebooster chamber'but insulicient to permit the pressure of the air withinthe booster chamber to be reduced Below the necessary value for forcingthe water out through the pipe 20 and into the tank 24. This adjustmentof the valve 31 is ob.1

tained manually by openingthe valve so' If for any reason the pressurewithin the' shell 14 becomes too great, as because of the stoppag of'the valve 31, the excessive pressure foriies open the blow-oil' valve35 and pertnits the air to escape from the upper pari) offthe shell 14until such pressure 1s reduced to normal.

The operation of 'the blowrevents thevexcess pressure froxn burstlng the booster Shelli I v' I By thearrangement described, the water may be forced horizontally for greatdistances, in a manner impossible hitherto ,with air-liftl pumps., andthe ratio of the submergence of the air nozzle 12 below the water levelin the wall to the total lift of the water is diminishedbecause it isonly necessa `that this ratio be maintained between't esubm'ergence' andthe .lift of the water into the booster shell. Moreover, the

water. vdischarged into the pipe 25' and reservoir-24 is substantiallyfree from ain I claim as his invention: 1.
